Question

21. Find the missing dimension in the dimension
strings below.

Answer 1

Required Answer :

Total length of string = 30'

According to the figure,

`\quad \twoheadrightarrow\sf { 30' = 15' + A + 9' } \\`

`\quad \twoheadrightarrow\sf { 30' = 24' + A} \\`

`\quad \twoheadrightarrow\sf { 30' - 24' = A} \\`

`\quad \twoheadrightarrow\underline{\boxed{\sf { 6' = A}}} \\`

Therefore, the missing dimension in the dimension strings is 6'.
